Concepts and challenges of creating, delivering and supporting services

What the syllabus expects

You must be able to explain how services are created and delivered through the service value system, and describe the practical pressures that make this hard.

Core concepts to name: the service value chain and its six activities (plan, improve, engage, design and transition, obtain/build, deliver and support); value streams as the specific combinations of activities an organisation actually uses; service offerings (goods, access to resources, service actions); service relationships built on provisioning, consumption and relationship management; and the utility/warranty split of value.

Challenges to describe: organisational silos and handover loss; legacy systems and technical debt; shadow IT and consumerised technology; variable demand against fixed capacity; integrating Agile, Lean, DevOps and ITIL ways of working; managing multiple suppliers; and the cost of poor quality versus the cost of getting it right first time.

Traps in questions

  • Utility is fit for purpose (what the service does); warranty is fit for use (how reliably, securely, capaciously it does it). A service that meets its specification but is unavailable during peak demand fails warranty, not utility.
  • The value chain is a generic model; a value stream is a real, end-to-end route for a specific demand type. Options that swap the two are wrong.
  • Value is co-created with the consumer, not manufactured and pushed by the provider. Be wary of any option that says the provider alone creates value.
  • Confusing outputs (delivered items) with outcomes (business results) and value (outcomes plus experience).

Worked example

A payroll system processes every calculation correctly (high utility) but is offline on the last working day of the month (poor availability warranty). Users call it a bad service even though the specification is met. Rule of thumb: ask "what does it do?" (utility) and "under what guaranteed conditions?" (warranty) - value needs both, plus good experience.
